Abstract
An over-the-air (OTA) measurement system for testing a device under test, with a plurality of feed antennas, a test location for the device under test, and a reflector array with a main reflector and a sub-reflector. The plurality of feed antennas face the sub-reflector. The reflector array is located such that a signal path is established between the plurality of feed antennas and the test location via the sub-reflector and the main reflector. The sub-reflector has at least one focal point. The plurality of feed antennas include a first feed antenna and at least one second feed antenna. The first feed antenna is associated with the focal point of the sub-reflector. The at least one second feed antenna is located offset from the focal point of the sub-reflector. Further, a method of testing a device under test over-the-air is described.
